Table 1: Relative intensities (partial ion yield - PIY) and kinetic energy U₀ release by fragments in the formic acid mass spectra, as a function of photon energy. Only fragments with intensity >0.1% were tabulated. The estimated experimental error was 10%
Table 2: Values of non-dissociative single ionization (photoionization) cross section ( $\sigma _{\rm ph-i}$ ) and dissociative ionization (photodissociation) cross section ( $\sigma _{\rm ph-d}$ ) of formic acid as a function of photon energy. The estimated experimental error was 30%. The photoabsorption cross section $\sigma _{\rm ph-abs}$ from Ishii & Hitchcock (1987).
